GLARELESS HEADLIGHT.

Application filed April 1, 1925. Serial No. 19,823.

. p This invention is a glareless headlightand consists of the novelfeatures herein shown, described and claimed.

An object is to make aheadlight having light deflectors in the form ofslats extending horizontally across the light area behind the lens andadapted to deflect the light forwardly and downwardly and to providemeans for adjusting the angularity of the 10, slats. v I r 4 Otherobjects and advantages will appear from the drawings-and specifications.The drawings illustrate the invention.

Figure 1 is a front elevation of the headlight embodying the principlesof my invention, the View being taken looking in the direction indicatedby the arrow lin Fig. 2. Fig. 2 is an enlarged vertical sectional detailon theline 22 of Fi 1.

20 Fig. 3 is afragmentary sectional detail on the. line 3-3 of Fig. 2and looking in the direction indicated by the arrow.

Fig. 4 is a fragmentary sectional detail on the line of Fig. 3and-looking in the direction indicated by the arrow.

. The details of construction and operation are as follows:

The frame 1, the reflector 2, the lamp '3, may be any of the ordinaryconstructions 30- forming a parabolic reflector or the like. A spacingring l is inserted against the usual packing 5 at the forward edge ofthe frame and reflector 1 and 2, a bearing opening or slot 6 is formedfrom the front edge of the ring 4 at the bottom and in line with theaxis. The deflector supporting ring 7 fits within the spacing ring a andhas an annular outwardly extending flange 8 fitting against the frontface of the spacing ring 4. A non-metallic packing ring 9 fits againstthe flange 8 and the lens 10 fits against the packing 9 and is held inplace by the ri1n':tI-.

A series of lightdeflectors 12 is mounted horizontally across thedeflector supporting ring 7. Each deflector 12 consists of a metal slat13 having pintles 14 and 15 extending from its ends and bearingsockets16 and 1'( mounted in the-ring 7 so that the slats may tilt about theaxis.

Notches 18 are formed from the front edges of the slatsat their forwardsides, an operating bar 19 fits loosely in these notches and pins 20 areinserted through the bar 19 and soldered against the edges of the slatsto pivotally connect the operating bar 19 to the slats and to connectthe slats together, so that as the bar 19 is moved upwardly ordownwardly, the deflecting angularity of the slats is varied. 1 The bar19 operates loosely in the slot or opening 6 and extends downwardlythrough the rim 11.

A supporting bracket 21- extends clown- 'wardlyfrom the rim l1. Abearing assembly 22 is supported by the bracket 21 and consists of aflange fitting against the backside of the bracket, an externally screwthreaded nipple 24 passing through bracket 21, a nut 25 upon the nipple24 against the bracket, a sleeve 26 extending backwardly from the flange28 and-having a chamber- 27 extending from its rear end to the plane ofthe flange 23 and a screw threaded hearing 28 extending through theflange 23 and nipple 24:.

An adjusting screw 29 is mounted in the screw threadedbearing 28 andextends into the chamber27 one way and extends beyond the nipple 24 theother way. A Bowden cable 30 has one end 33 of the wire insertedintoethe end'of the screw 29 and soldered or otherwise fastened and hasthe end.32 of the housing inserted into the chamber 27 and secured by aset screw 31.

. A dial 34 sets against the front face of an instrument board 35 inconvenient position to be manipulated by the operator of the motorvehicle. A knob 36 is fornled integral with the dial or secured thereto.A stem 37 extends from the knob and dial through the board 35. Attachingplate 38 is secured to the opposite side of the board 35 from the dial.A bearing 39 extends from the plate den cable wire extends into the endof the stem 37 and is soldered or otherwise secured 38 and the rear endof the stem 37 extends into the bearing 39. The end 10 of the Bowpivot45: one end of the bell crank level it has a slot 46' and is forked orbifurcated to receive the lowerend of the operating bar 19 and apin a7is fixed in the bar 19 and operates 1. the slot A6 so that as the bellcrank lever is rocked the bar 19 moves up .tatcs the screw 29 to moveand down to change the angularity of the deflectors 12.

A connecting rod i8 has ahead at!) fitting against the end of the screw29 and a union nut .50 is placed upon the rod 18 against the head 49 andscrewed upon the screw 29 to make a swivel connection between the rod 18and the screw 29. The outer end of the rod #18 is connected to the lowerend of the bell crank lever 4-1 by a pivot 51.

lVhen the operator desires to change the angularity of the deflectors12, he manually engages the knob 36 and rotates the dial 3- to thedesired extent and this operation rothe screw forwardly or backwardlythrough the bearing 2-8 thereby operating the bell crank lever 44, tooperate the bar 11), to raise or lower the forward edges of thedeflectors 12, thereby swinging the deflectors upon the pivots 1-1 and15.

The deflectors 12 consisting of a series of slats 13 of various lengthsas required to fit in the ring 7, are opaque and preferably black upontheir upper faces and are silvered on their lower faces. The slatsnormally set at an angle of about degrees relative to a vertical orhorizontal plane, with their silvered side's downwardly and towards thelight, so that the rays 52 coming from the lamp 3 and deflected by theparabolic deflcctor :2 will strike the silvered faces of the slats'andbe deflected forwardly and downwardly as indicated by the arrows 53 andthe angularity of the arrows 53 may be accurately adjusted bymanipulating the knob 36 and adjusting the angularity of the de flectors12.

If desired the deflectors may be adjusted to horizontal positions sothat the light rays will go straight through.

Thus I have produced a glareless headlight having a series of pivotallymounted deflectors with their axis extending horizontally and havingmeans for adjusting the angularity of the deflectors from the operatorsseat, the means being mounted upon the dash or instrument board of thevehicle.

Various changes may be made Without departing from the spirit of myinvention as claimed.

I claim:

1. A headlight having a frame, a series of deflector slats pivotallymounted within said frame, an operating bar connected to each ofsaidslats, a bell crank lever pivotally supported from the frame, one end ofthe lever being connected to the operating bar, a supporting bracketattached to the frame, an internally screw threaded hearing mounted onsaid supporting bracket, an adjusting screw threaded therein, a rodswivclly connected to said screw, the rod being connected to one end ofthe bell crank lever and a flexible remote control device connected tosaid screw, adapted to rotate same and through the operation of the rodthe bell crank and the operating bar control the slats.

2. A headlight comprising in combination a frame of suitable shape for aheadlight, a spacing ring positioned on the outer edge of the frame, adeflector supporting ring mounted on the spacingring, a plurality ofdeflector slats pivotally mounted in the. supporting ring, an operatingbar connected to the edge of each of the slats, a rim positioned outsideof the spacing ring and the supporting ring, a bell crank leverpivotally connected to the said rim, a supporting bracket attached tothe rim, an internally screw threaded bearing titted in said bracket,the bearing having a chamber, an adjusting screw threaded in the bearingand having one end extending into the. chamber, a rod swivelly connectedto the outer end of the screw. the said rod being connected to the freeend of the bell crank lever, a fixed flexible tube having, one endsecured in the chamber of the threaded bearing and a flexible wirehaving a remote control device thereon extending through the tube andbein; secured to the inner end of the adjusting screw.

In testimony whereof I have signed my name to this specification.
